WGU C182 Introduction to IT (v3)
hardware, software, and users.
Information Technology has three main components:




the task of gathering data and processing it into information, the ability to
disseminate information using technology, the technology itself that permits
these tasks, and the collection of people who are in charge of maintaining the
IT infrastructure (the computers, the networks, and the operating systems).
Generically, we will consider IT to be the technology used in creating,
maintaining, and making information accessible. In other words, IT combines
people with computing resources, software, data, and computer networks.
IT is a term used to describe several aspects:




someone who is in charge of some portion of the IT infrastructure.
administrator




Administer the computers in an organization; install software; modify/update
operating system; create accounts; train users; secure system; troubleshoot
system; add hardware.

- installing and configuring new hardware and troubleshooting hardware
including the network
- installing and configuring new software including updating new operating
system (OS) patches, and troubleshooting software
- providing documentation, support, and training for computer users
- performing system-level programming as necessary (usually through

is in charge of all aspects of the computer network. The network
administrator's duties include physically laying down cable, making
connections, and working with the network hardware (for instance, routers and
switches). The network administrator also has to configure the individual
machines to be able to communicate via the network.

must stay informed of the many different types of attacks, such as denial of

security administrator




also known as a webmaster, but more precisely referred to as a web server
administrator. This role is responsible for maintaining websites, which differs
from the development of websites. Specifically, the web administrator must
install, configure, maintain, secure, and troubleshoot the web server.

training and help desk support.
The IT person is responsible for teaching new and current users how to use
the IT infrastructure (i.e., training).
Support usually comes in two forms:




AD
data that can be organized, manipulated, filtered, sorted, and used for
computation.

, often defined as processed data. That is, raw data are the input and
information is the output of some process. In fact, more generically, we should
think of information as any form of interpreted data.
Information




the input directly received by the human (or computer). Data typically are
thought of as signals.
Data are




information that has been put to use.
a synthesis of several different sources of information.
information placed into a context, perhaps the result of experience gained
from using information.
refined information such that the user is able to call forth only relevant portions
of information when needed.
Knowledge is sometimes defined as




provides a social setting to knowledge.
an understanding of "why"—whether this is "why things happened the way
they did" or "why people do what they do."
can only come by having both knowledge and experience.
